加严环境空气质量标准是否不利于经济发展？生态环境部回应

Core Viewpoint - The Ministry of Ecology and Environment has released a draft for stricter air quality standards, raising concentration limits for PM2.5, PM10, SO2, and NO2, which may impact economic and social development, but past experiences suggest that stricter standards can improve air quality and promote high-quality economic growth [1][2]. Group 1: Air Quality Improvement - The revision of air quality standards has significantly improved national air quality, with a 36% decrease in average PM2.5 concentration and a 68% reduction in heavy pollution days over the past decade, while GDP increased by 63% and the number of vehicles rose by 111% [1]. - The implementation of stricter air quality standards has led to four strategic shifts in air pollution control: from total pollutant emission control to air quality improvement, from single pollutant control to multi-pollutant coordination, from industrial source control to comprehensive management of various pollution sources, and from local pollution control to regional joint prevention and control [2]. Group 2: Economic and Social Development - The revised standards are expected to have a limited direct impact on production activities, as air quality standards focus on goal orientation and strategic guidance rather than strict emission limits [2]. - The process of achieving air quality standards is gradual, with supporting policies, funding, and technologies being implemented progressively to ensure a smooth transition without disrupting economic stability [2]. - Long-term benefits of stricter standards include further reductions in PM2.5 levels, improved public health outcomes, and the promotion of new production capacities in sectors like electric vehicles and clean energy, facilitating a green and low-carbon transition in industries [3].
